Ion Dissociation in the Drift Tube of a Time-of-Flight Mass Spectrometer: II. Fixed Δt Method , of Identifying Fragment Ions

摘要

The fixed At method of identifying fragment ions formed in the drift tube (analyzer) of a time-of-flight mass spectrometer depends on determining the potential barrier characteristics required to produce a preselected flight-time shift. It is both simpler and more accurate than the comparison method used in a previous series of experiments.
